High-Explosive Ditching from Linear Charges

High-Explosive Ditching from Linear Charges

Date: July 1961
Creator: Carlson, R. H.
Description: Abstract: "Weights of linear high-explosive charges fired on the Yucca Lake playa of the Nevada Test Site varied from 0.23 to 42.7 pounds per foot. Crater and ditch dimensions and volumes resulting from these shots, fired during the fall of 1959 and spring of 1960, are presented here as a function of charge burst depths. Scaling relationships determined are as expected; i.e., square-root scaling of linear-charge weight per foot for ditch width and depth and a direct linear-charge weight relationship to ditch volume are obtained. Permanent ground surface displacement varies as the -3.22 power of the scaled distance from the charge. Detonation effects, charge shape effects, ditch erosion, and ditch cross sections are discussed. The appendixes present Toboggan data, results of soil investigation, and mathematical treatment given the data."

High Explosive Crater Studies: Tuff

High Explosive Crater Studies: Tuff

Date: April 1961
Creator: Murphey, Byron F.
Description: Abstract: "Spherical charges of TNT, each weighing 256 pounds, were exploded at various depths in tuff to determine apparent crater dimensions in a soft rock. No craters were obtained for depths of burst equal to or greater than 13.3 feet. It was deduced that rock fragments were sufficiently large that charges of greater magnitude should be employed for crater experiments intended as models of nuclear explosions."

Stress Pulse-Trains from Multiple Reflection at a Zone of Many Discontinuities: a Notation for Machine Solution

Stress Pulse-Trains from Multiple Reflection at a Zone of Many Discontinuities: a Notation for Machine Solution

Date: August 1962
Creator: Reed, R. P.
Description: Abstract: "Presented in this report is a numerical method by which may be calculated the amplitudes of the trains of pulses that result when a single simple stress pulse encounters a zone of many abrupt discontinuities in a slender rod. The notational scheme employed enables the system of multitudes of individual progagating waves to be studied in terms of analogous number sets which may be mechanically generated. The notational concept and related operational rules, described in this report, have been used to program the problem for solution with the IBM 704 computer. The program is briefly discussed. Illustrative examples were computed for rods of two to ten discontinuities. These were compared with a pulse reflected in a rod of an unlimited number of steps."

Irreducible Representations of Line Groups: the Dynamics of Polymer Chains

Date: December 1961
Creator: Lawson, Katheryn Emanuel & Crosby, G. A.
Description: Abstract: "The symmetries of infinite polymer chain molecules are discussed using the concept of line groups. Explicit directions are given for obtaining the irreducible representations of line groups employing the formalism developed for three-dimensional space groups. Line groups containing primitive and nonprimitive operations are discussed. Detailed considerations of the line group Vh are given with specific applications to the polyethylene molecule. Directions for generating symmetry-adapted vibrational coordinates for chain molecules are outlined."

A Scale-Model Experiment of the Crater Produced Through Terrain of Randomly Varying Elevation by Row Charges

A Scale-Model Experiment of the Crater Produced Through Terrain of Randomly Varying Elevation by Row Charges

Date: November 1962
Creator: Vortman, Luke J.
Description: Abstract: "A scale-model experiment was made to check the application of charge spacing rules developed from earlier studies to terrain of randomly varying elevation. Since a prominent possible peacetime use of nuclear explosives is the excavation of a trans-Isthmian canal, the model used was a portion of such a route. The experiment resulted in nearly the desired linear crater dimensions; the spacing rules developed for level trerain give a satisfactory channel when applied to terrain with elevations varying in random fashion."

Construction of a Sea-Level, Transisthmian Canal Using Nuclear Explosives

Construction of a Sea-Level, Transisthmian Canal Using Nuclear Explosives

Date: February 1964
Creator: Vortman, Luke J.
Description: Partial abstract: "This report is based: (1) on information developed in earlier high explosive experiments which determined the optimum spacing and burial depth of charges in a row to produce a channel uniformly wide and deep, and (2) on the Sedan and Danny Boy experiments, which provided data on dimensions of nuclear craters in both soil and basalt rock. This information has been combined with the 1947 route surveys of the Panama Canal company, and estimates have been made not only of the number and yield of nuclear explosives required to excavate a Transisthmian canal with nuclear explosives, but also of the cost of the explosives and the cost of their replacement."

Geologic Summary of the Central Valley of California with Reference to the Disposal of Radioactive Waste

Geologic Summary of the Central Valley of California with Reference to the Disposal of Radioactive Waste

Date: June 1960
Creator: Repenning, Charles Albert
Description: From introduction: This report describes the geology of the area only to the extent necessary for preliminary evaluation of the possibilities for the disposal of liquid radioactive waste by injection through deep wells. Their value will increase with development of extensive commercial production of atomic power and attendant creation of radioactive waste from the processing of spent fuel elements. The disposal of liquid waste in deep reservoirs is only one of several possibilities that must be considered.

Estimating Safety Probabilities from Fallout Forecasts for Nevada Test Site

Estimating Safety Probabilities from Fallout Forecasts for Nevada Test Site

Date: July 1, 1960
Creator: Reed, Jack W.
Description: Abstract: "Available data on wind persistence and wind forecasting capability have been applied in estimating the probability of a fallout pattern shifting from an uninhabited safe sector into a populated region. Safety probability is computed from win variability, forecasting accuracy, initial height and particle size of radioactivity landing at a point in the predicted fallout pattern, predicted wind speed, length of forecast period, and safe-sector angular width."
